ESCRT complexes form the main machinery driving protein sorting from endosomes to lysosomes. The core domain of the Vps23 subunit of the heterotrimeric ESCRT-I complex is a helical hairpin sandwiched in a fan-like formation between two other helical hairpins from Vps28 (Pfam:PF03997) and Vps37. Vps23 gives ESCRT-I complex its stability [1].

This family represents a conserved region approximately 150 residues long within a number of eukaryotic proteins that show homology with Drosophila melanogaster Modifier of rudimentary (Mod(r)) proteins. The N-terminal half of Mod(r) proteins is acidic, whereas the C-terminal half is basic [1], and both of these regions are represented in this family. Members of this family include the Vps37 subunit of the endosomal sorting complex ESCRT-I, a complex involved in recruiting transport machinery for protein sorting at the multivesicular body (MVB). The yeast ESCRT-I complex consists of three proteins (Vps23, Vps28 and Vps37). The mammalian homologue of Vps37 interacts with Tsg101 (Pfam: PF05743) through its mod(r) domain and its function is essential for lysosomal sorting of EGF receptors [2].

The endosomal sorting complex required for transport (ESCRT) complexes play a critical role in receptor down-regulation and retroviral budding. A new component of the ESCRT-I complex was identified [1], multivesicular body sorting factor of 12 kD (Mvb12), which binds to the coiled-coil domain of the ESCRT-I subunit vacuolar protein sorting 23 (Vps23) [1].
